Denmark’s gambling regulator, the Danish Gambling Authority (DGA), has reported a licensed online casino operator to the police over concerns that it failed to uphold anti-money laundering regulations in the case of one high-spending player.

The DGA has referred the unnamed company to Denmark’s State Prosecutor for Serious Economic and International Crime (FIU), asking it to investigate the operator for failing to comply with regulations after a player spent millions gambling between March 2012 and September 2013.
